Well, then the first question that needs to be answered, which model of PDP-11 was that code expected to run on, because the results will differ depending on that. Also, what kind of memory? (I would guess some old, small core memory boards.) The PDP-11 execution speed really does vary based on

L.S. Actually where this is important, is when using Pdp11 based ANF10 workstations in the Tops10 realm. When starting up, the Anf10 software on the pdp11 sim test various devices for functionality thereby using instruction count based loops etc. When all the devices necessary (paper tape rea
